Lineup news from the Avalanche (22-22-11) morning skate at the Pepsi Center is here. Dallas (26-21-8), which beat Florida 2-0 at home Friday night, did not have a morning skate and is going without forwards Tyler Seguin (knee), Ales Hemsky (lower body), Patrick Eaves (concussion) and Antoine Roussel (suspension) against the Avs. Here’s the video of Seguin’s injury (out 2-4 weeks) late in Friday’s game against the Panthers:

I wanted to give that enough shelf life before posting anything from Wednesday at the Avs’ facility. The Avs returned from Dallas a little after midnight Wednesday, following their tough 3-2 loss to the Stars, who scored late in the third period on a semi-breakaway. Only the scratches from that game (Ryan Wilson, Nate Guenin, Brad Malone) and goalies Semyon Varlamov and J.S. Giguere skated Wednesday. Coach Patrick Roy said Varlamov will start Thursday against the visiting Edmonton Oilers and Guenin will return to the lineup after being a healthy scratch for the first time this season.

About the headline: Matt Duchene knows he had a good showing in the back-to-back, two-city series with the Stars that was attended by Canada’s top Olympic official, Steve Yzerman. As Adrian Dater wrote in the Game 2 game notebook, Yzerman was at that game, but Duchene said Yzerman was also at Tuesday’s game in Denver, a 6-2 Colorado victory (a game I covered but did not see Yzerman).

When: The Avalanche and Dallas Stars have an old-fashioned, barn-to-barn series Monday and Tuesday, with the teams meeting Monday at the Pepsi Center.

What’s up: Seguin is in his first year with the Stars after a somewhat shocking trade from the Boston Bruins, a deal that sent Loui Eriksson to Boston.

Background: Drafted second overall by Boston in 2010, part of the Bruins’ bounty in trading Phil Kessel to Toronto and the Maple Leafs’ subsequent bad season, Seguin posted only 22 points in 74 games with Boston during his rookie season. But he had 29 goals and 67 points his sophomore season. It seemed he would be a fixture for years to come in Boston. But a so-so third season prompted Bruins management to give up on him and ship him to Dallas. He has 17 goals and 31 points in 29 games.

Dater’s take: Count me among those who think the Bruins will regret the trade. Eriksson is a good player, but he’s become concussion-prone. Seguin has major talent, and he’s only 21. He has taken some deserved knocks for his off-the-ice behavior but, again, he’s only 21.

Players with Seguin’s offensive talent don’t come around often, and Boston became impatient with him. But he’s proving to be a point-a-game guy with the Stars and he’s only going to get better.
